Another high-volume number of arrests in a Carter County methamphetamine investigation have been reported. Sheriff Chris Mathes says “Operation: Street Sweeper” is another step in the continuing battle against the infectious affects of methamphetamine manufacture, distribution and sales. Eighteen Persons have been arrested and the search continues for another 12 still at large. No Injuries or incidents have been reported in the round up. The Sheriff pointed out that methamphetamine users are becoming a subculture in many areas of Tennessee. He added there's a lot of networking between those who buy manufacturing supplies, actually do the cooking, and use and distribute the drug. (CS)
